1 Claim.

This specification will disclose an improved book construction of thekind having a back portion and two hinged covers, between which all thepages, or filler, may be bound or unbound as desired, for changing thebook contents. This kind of book construction is known and appears invarious prior art forms. The new form to be disclosed is one havingcertain combinations with definite advantages, as will appear from thefollowing description.

Fig. 1 is a plan view of book covers and back portion without contents;

Fig. 2 is a plan View of the book pages arranged for insertion as thebook contents;

Fig. 3 is an edge view of the book with all elements assembled as aunit;

Fig. 4 shows a rod suitable for fastening the book contents in the bookbinder;

Fig. 5 is a plan and Fig. 6 is a sectional View on line 66 showing themetal plate mounted in the back portion of the binder; and

Fig. '7 is a detail view showing the assembly of the metal parts only.

The book binder of Fig. 1 is technically known as a case. It consists ofthe two covers I and 2 hinged to the curved back portion 3, all in oneunit. In making up such a case for this invention, the curved metalplate 4 of Fig. 5 is fastened into the back portion, preferably bylaminating it with the usual binding strips on the outside, as bookbinders will understand. Spaced bridges 6 are stamped out of this metaland extend upwardly so as to make small open arches on the inside of theback portion, see Fig. 6. This arrangement completes the case or binderseen in Figs. 1 and 3.

The book contents of Fig. 2 is an arrangement of sheets or pages 7, withspaced holes along their binding margins. A single helically coiledbinding wire 8 is threaded through these holes, the wire having thepitch equal to the space between the holes. The binding of paper pads inthis 1 way, as shown in Fig. 2, is well known and widely this wayremovably fastened in the binder case, v

see Fig. 3.

The combination of parts is a simple and effective one to make a veryuseful book. All that is added to the binder case, in the disclosed andpreferred form, is'a single metal stamping 4.

The pad or book contents of Fig. 2 is of a highly desirable and knownform of book unit. The binder case and its contents are brought into orout of book combination by the mere insertion or removal of one rod 9 toengage or disengage the two main elements. The rod may be so placed asto fit rather snugly between the binding wire coils 8 and the spacedarches 6. If this is provided for, as well as for a rather snug fit ofthe width of the arches between the coils, the assembly will be made inthe preferred form. There will be enough spring action between the partsall along the back, due particularly to the springy nature of the coiledwire, as to hold everything without the shifting about in use which sooften gives a sloppy, unsubstantial impression to removable binders. Thenew arrangement gives a removable binder for the particular kind of bookfiller so highly desirable to use on account of the inexpensive andefficient way in which the pages are bound to turn over easily and lieflat. The whole book in the form now disclosed and seen in Fig. 3 is anew and useful article in which the elements all coact.

Having described the invention and how it may be practiced, thefollowing claim is made for its protection.

I claim: I

In a book structure-of the kind in which the filler sheets are hung onthe closely spaced coils of a single binding wire and fastened to theback panel of the binder case by a rod Inside the coils and fastened tothe back panel, that construction in which the back panel is curvedtransversely, a sheet metal stiffening plate built into the back panelover its whole area and shaped to hold the back panel form, a series ofarches spaced along the whole length of the back panel struck up fromthe sheet metal of the back panel, the arches metal plate functions toboth hold the curved form of the back panel as a functional part of saidback panel and as a rod holding means by reason of its integral archesto nest the wire coils closely in said curved back panel under the rod 5and between the arches.
